From the moon where does earth looks?

If you outstrech your arm, your little finger will just cover the moon. If you were on the Moon & outstreched your arm, you would have to use your thumb to just cover the earth. The earth also go through the same phases of full to new as your position, due its orbit, changes the relative positions of the earth to the sun from your view point.
You would see the blue oceans, continents, ice covered poles & cloud formations. Sadly you wont see the great wall of China or any evience of us!
